Background and method: Parenting and parenting styles are in favor of authoritative parents compared with non-authoritative parents. These parents display higher levels of both responsiveness and demandingness. We studied the aspect of demandingness using a questionnaire aimed at children aged between 1 and 4 years. 82 Children with recurrent respiratory infections (RRI) and 399 control children were included. Results: Parents of RRI children regulated the quantitative dietary intake of their child less;likewise they gave less stimulation to their children to eat. They also taught their children less on what they can or cannot touch and they argued more with their children (all p mes to simple rules like watching television or not, the parents of RRI children were very clear. There were however no differences in rules about television watching, computer time or bedtimes. Conclusions: Our study shows that parents of children with RRI are less demanding in complex pedagogic situations that ask for creativity from the parents. However, they are demanding with respect to simple rules. We found no child factors that could explain why children give their parents a hard time. We hypothesize that the parents of RRI children could be less capable of handling complex pedagogic situations (even more complicated by the infections) instead of being unwilling.

A three-dimensional model of near-surface shear-wave velocity in the deep alluvial basin underlying the metropolitan area of Las Vegas, Nevada （USA）, is being developed for earthquake site response projections. The velocity dataset, which includes 230 measurements, is interpolated across the model using depth-dependent correlations of velocity with sediment type. The sediment-type database contains more than 1 400 well and borehole logs. Sediment sequences reported in logs are assigned to one of four units. A characteristic shear-wave velocity profile is developed for each unit by analyzing closely spaced pairs of velocity profiles and well or borehole logs. The resulting velocity model exhibits reasonable values and patterns, although it does not explicitly honor the measured shear-wave velocity profiles. Site response investigations that applied a preliminary version of the velocity model support a two-zone ground-shaking hazard model for the valley. Areas in which clay predominates in the upper 30 m are predicted to have stronger ground motions than the rest of the basin.

A new portable in situ flume(PISF) for measuring critical bed shear stress(CBSS) was developed in this study. The PISF consists of an open bottom sediment erosion chamber and an electrically-driven *** most existing in situ flumes with similar designs, the new PISF does not rely on monitoring the flow conditions or particle density in the sediment erosion chamber; instead, it is a pre-calibrated *** calibration was performed by first determining CBSS of various selected sediment samples of known particle size and density(using the law of the wall), based on flow velocity-depth profiles measured in a6 m straight open-channel flume using a Particle Image Velocimetry(PIV) system. These same particles of known CBSS were then used in the new in-situ flume under controlled lab conditions to obtain a series of calibration curves of CBSS vs. pump electrical power. A wide variety of particle types and sizes(simulated sediments) were used in this two-step calibration procedure to widen CBSS measurement range and simulate cohesive force effects. The size of the PISF is much smaller and more practical than other similar devices as lamellar flow conditions are not required and it can be applied to a wide range of sediment types including cohesive sediments.

Cohesin is a multiprotein complex that not only is essential for cell division but also has key roles in genome organization that underpin its gene regulatory *** mutations of genes encoding cohesin subunits occur in myeloid malignancies at 10%–12%(Kon et al.,2013),and the frequency of cohesin mutation in Down syndrome-associated megakaryoblastic leukaemia is even higher(~50%)(Yoshida et al.,2013).Cohesin insufficiency reinforces stem cell programmes and impairs differentiation in haematopoietic stem cells(mazumdar et al.,2015;mullenders et al.,2015;Viny et al.,2015).The STAG2 subunit of cohesin is the most frequently mutated in myeloid malignancies(Kon et al.,2013).In contrast to other cohesin subunits,complete loss of STAG2 is tolerated due to partial compensation by ***2 and STAG1 have redundant roles in cell division(Benedetti et al.,2017;van der Lelij et al.,2017).However,cohesin-STAG1 and cohesin-STAG2 have non-redundant roles in facilitating 3D genome organization to delineate tissue-specific gene expression(Kojic et al.,2018).
